IMS TM is terminating normally (for example, /CKPT FREEZE command).
B
IMS TM is terminating abnormally.
C
Db2 is terminating in a quiesce fashion (for example, Db2 stop quiesce command).
D
Db2 is terminating abnormally.
E
The connection between IMS TM and the Db2 subsystem is terminating; however, both subsystems remain operational.
All DSNM messages are sent to the IMS master terminal operator (MTO) and to the appropriate MVS console.

System action

The connection between IMS TM and Db2 terminated.IMS TM transactions can no longer access Db2 resources.

Operator response

Notify the system programmer.

System programmer response

Reason code A, C, or E makes this an information message. Reason code D indicates that a serious problem occurred in the Db2 subsystem, and that the SYS1.LOGREC should be examined. For reason code B or D, determine the failing subcomponent.

If you suspect an error in Db2, you might need to report the problem. For information about identifying and reporting the problem, see Collecting diagnostic data.

Problem determination

SYS1.LOGREC and/or dump information may be available for reason codes B and D.
